IEC 60079-15:20 17 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 60079-15:20 17规定了保护类型为“n”的II类电气设备的构造、测试和标记要求，包括:用于爆炸性气体环境的密封装置“nC”、气密密封装置“nC”、非易燃部件“nC”和限制性呼吸外壳“nR”。IEC 60079的这一部分适用于额定输入电压不超过15 kV r的电气设备。多发性硬化症。交流或DC，包括Ex产品的内部工作电压超过15kV的地方，例如用于HID灯具的启动器。IEC 60079的这一部分补充和修改了IEC 60079-0的一般要求，表1（第1条）中指明的除外。如果IEC 60079本部分的要求与IEC 60079-0的要求相冲突，则以IEC 60079本部分的要求为准。第五版取消并取代了2010年出版的第四版，构成了技术修订。有关5.0版与文档上一版之间技术变更的完整列表，请参阅文档的前言。 关键词:保护类型“n”的II类电气设备

IEC 60079-15:2017 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 60079-15:2017 specifies requirements for the construction, testing and marking for Group II electrical equipment with type of protection “n” which includes; sealed devices “nC”, hermetically sealed devices “nC”, non-incendive components “nC” and restricted breathing enclosures “nR” intended for use in explosive gas atmospheres. This part of IEC 60079 applies to electrical equipment where the rated input voltage does not exceed 15 kV r.m.s. AC or DC including where the internal working voltages of the Ex product exceeds 15 kV, for example starters for HID luminaires. This part of IEC 60079 supplements and modifies the general requirements of IEC 60079-0, except as indicated in Table 1 (Clause 1). Where a requirement of this part of IEC 60079 conflicts with a requirement of IEC 60079-0, the requirement of this part of IEC 60079 takes precedence. This fifth edition cancels and replaces the fourth edition, published in 2010, and constitutes a technical revision. Refer to the Forward of the document for a complete listing of the technical changes between edition 5.0 and the previous edition of the document.
